About this study

Official title: First-In-Human Intracoronary Dual-modal Optical Coherence Tomography and Fluorescence Lifetime Imaging (OCT-FLIM) In Patients Undergoing Percutaneous Coronary Intervention

Patients will undergo intracoronary imaging using combined optical coherence tomography-fluorescence lifetime imaging (OCT-FLIm) during percutaneous coronary intervention, and the obtained imaging data will be used to assess the efficacy of this dual-modal catheter imaging strategy in characterizing high-risk plaque.

Read the detailed description

Fluorescence lifetime imaging (FLIm) is a novel imaging approach allowing label-free biochemical characterization of atherosclerotic plaque. A combined optical coherence tomography (OCT) and FLIm that can provide a simultaneous structural and biochemical assessment of atheroma has been constructed successfully. This study sought to investigate whether the dual-modal intravascular OCT-FLIm is able to characterize high-risk plaques in patients undergoing percutaneous coronary intervention.

Forty patients with multivessel coronary artery disease, who had at least one obstructive lesion (>70% diameter stenosis) that is considered suitable for PCI, will be included in the study. Culprit and mildly stenotic non-culprit plaques will be imaged using OCT-FLIm catheter.

Six-month follow-up assessment is systematically scheduled in all patients to assess temporal changes in FLIm signatures according to treatment strategies (medical therapy, interventional therapy etc).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fluorescence lifetime measurement of plaque inflammation in the target/culprit or non-target/non-culprit lesion (nanosecond)

    Difference in fluorescence lifetime measurement reflecting plaque inflammation according to pre-specified plaque subtypes

    Measured: day 1

Secondary outcomes (2)
  1. Fluorescence lifetime measurement of healed plaque in the target/culprit or non-target/non-culprit lesion (nanosecond)

    Difference in fluorescence lifetime measurement reflecting healed property according to pre-specified plaque subtypes

    Measured: day 1

  2. Fluorescence lifetime measurement of calcification in the target/culprit or non-target/non-culprit lesion (nanosecond)

    Difference in fluorescence lifetime measurement reflecting superficial calficiation according to pre-specified plaque subtypes

    Measured: day 1

Questions about this trial

What is this clinical trial studying?

A study testing Dual-modal OCT-FLIm in people with Atherosclerosis Coronary Artery With Angina Pectoris and Atheroscleroses, Coronary, run by Korea University Guro Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fluorescence lifetime measurement of plaque inflammation in the target/culprit or non-target/non-culprit lesion (nanosecond) (time frame: day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04835467, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Dec 2023.
